XINGYANG HONGYUN MACHINERY developped the integrated wood chipper and crusher machine. It can not only make wood chips, but also make sawdust. This wood crusher is suitable for crushing large wood log.

Material for biomass briquetting

The best materials for briquetting are sawdust and other woody residues, because these contain a high proportion of lignin. However, most dry agricultural residues can be used if they are ground into a coarse powder. Grain straw and dried grasses do not make good briquettes on their own, but work well when mixed with woody materials to provide the lignin. Bagasse, shells (such as from peanuts) husks (such as rice husks and corn cobs) and pine needles make reasonable briquettes. However rice husks are abrasive due to their silica content, and can reduce the life of machine components.
